Texas Instruments TPA6120A2DWPR High Fidelity Stereo Headphone Driver is a single-channel, low noise, wide bandwidth Class-D amplifier designed to drive high-performance headphones. The device is capable of delivering up to 108 mA of continuous output current, which is more than enough for the majority of headphones. It offers three gain settings of -6 dB, 0 dB, and 8 dB, allowing it to accurately reproduce a wide range of music. The device also features advanced engineering features such as Adaptive gain, which allows the amplifier to dynamically adjust the gain to match the input signals level. Furthermore, the device features wide supply voltage range of 1.8V to 5.5V, allowing it to operate in a wide range of operating environments. In addition, it also features a current limiting protection to guard against short-circuit conditions, ensuring the device will operate safely and reliably.
